What Does Code B1321 Mean? DTC B1321 signifies a specific fault within the vehicle’s body control system, indicating a “Driver Door Ajar Circuit Short To Battery.” This is a Body (B) type code, meaning the issue resides within the vehicle’s body electrical systems, typically monitored by the Body Control Module (BCM), Generic Electronic Module (GEM), […]

What Does Code B1322 Mean? Diagnostic Trouble Code (DTC) B1322 signifies that the vehicle’s Body Control Module (BCM) or General Electronic Module (GEM), depending on the vehicle manufacturer and architecture, has detected a persistent short to ground in the electrical circuit dedicated to monitoring the driver’s door ajar status. This subsystem is crucial for various […]

What Does Code B1323 Mean? Diagnostic Trouble Code (DTC) B1323 specifically indicates a fault within the Door Ajar Lamp Circuit. This code is typically set by the vehicle’s Body Control Module (BCM) or General Electronic Module (GEM), rather than the Powertrain Control Module (PCM/ECM), as it pertains to a body electrical system. The BCM/GEM is […]

What Does Code B1324 Mean? DTC B1324 signifies a detected open circuit condition within the Door Ajar Lamp circuit. This is a manufacturer-specific (B-body codes) diagnostic trouble code indicating a fault primarily monitored by the Body Control Module (BCM), or potentially an Instrument Cluster Module (ICM) or other dedicated door module, depending on the vehicle […]

What Does Code B1325 Mean? Diagnostic Trouble Code (DTC) B1325, categorized as a Body Control Module (BCM) or General Module (GM) specific code, signifies a fault within the vehicle’s door ajar monitoring system. Specifically, it indicates that the BCM has detected an abnormal condition where the circuit responsible for indicating a door ajar status, or […]

What Does Code B1326 Mean? DTC B1326 signifies “Door Ajar Lamp Circuit Short To Ground.” This code is typically set by the vehicle’s Body Control Module (BCM), General Electronic Module (GEM), or Smart Junction Box (SJB), depending on the vehicle manufacturer and architecture. These control modules are responsible for monitoring the status of various door […]

What Does Code B1327 Mean? DTC B1327 signifies a detected circuit failure within the passenger door ajar sensor system. This code is typically set by the Body Control Module (BCM) or General Module (GM), which is responsible for monitoring the status of the vehicle’s doors. The passenger door ajar switch, often integrated directly into the […]

What Does Code B1328 Mean? DTC B1328 indicates an electrical malfunction within the passenger door ajar circuit, specifically signaling an open circuit condition. This code is typically set by the Body Control Module (BCM), or in some vehicle architectures, a dedicated Door Control Module (DCM), which monitors the status of door ajar switches. The passenger […]

What Does Code B1329 Mean? DTC B1329, “Passenger Door Ajar Circuit Short To Battery,” indicates that the Body Control Module (BCM), or in some vehicle architectures, the General Electronic Module (GEM), has detected an abnormal voltage condition on the circuit associated with the passenger side door ajar switch. Specifically, the BCM is observing a voltage […]

What Does Code B1330 Mean? DTC B1330 indicates a specific electrical fault within the passenger door ajar circuit, signalling a Short To Ground. In modern vehicles, the passenger door ajar switch is typically monitored by the Body Control Module (BCM), rather than directly by the Engine Control Module (ECM) or Powertrain Control Module (PCM). The […]
